Title: Membrane-type dehumidifier
Inventor: SUZUKI TOSHIHIRO
IPC: B01D63/00
Filed: 1995-03-16
Abstract: PURPOSE: To provide a membrane-type dehumidifier which can be made more compact. CONSTITUTION: This membrane-type dehumidifier 21 consists of a supply/exhaust block 22 with an intake port 3 and a discharge port 4 of a wet gas which are subdivided by a diaphragm 22a, a body 23, a membrane module 7 of a U bent form and a flow path case 24. A purge passage 30 for supplying a purge gas for dehumidification is provided at a position which is apart horizontally from a port opening direction in the supply/exhaust block, and the diaphragm 22a is thinned by making the ports 3, 4 close to each other. Thus, the length of the supply/exhaust block 22 in the port opening direction is shortened. As the length of the block 22 in the port opening direction is short, the dehumidifier can be made more compact.

IPC: H01L21/68
Filed: 1990-03-30
Abstract: PURPOSE:To realize in one process the reduction of adhering force and the separation of a chip by irradiating each part of the chip where the chip is adhered and fixed with an energy beam from the opposite side to a tape adhering surface. CONSTITUTION:Once an adhering tape 16 to which chip components 15 are fixed is set to a pick-up device, a single chip component is positioned with respect to a through-up pin 11, a collet 12, and a projector part 13a.

Title: Ink jet recording device
Inventor: KAWAMURA YOSHII
IPC: B41J2/045
Filed: 1978-07-14
Abstract: PURPOSE:To shorten an ink returning period and improve a response frequency by setting a flection device, bending due to an electrical operation, in an ink supply- preparation room. CONSTITUTION:An ink supply-preparation room 5 is improved to have a piezo element 14 as in an ink room 6 with an opening hole 13 to the atmosphere at one end of the room. Due to the effect of the piezo element 7 set in the ink room 6, the liquid pressure in the ink room 6 becomes negative, forming into ink drops and drawing the ink discharged from a nozzle 8. In conformity with this, a pulse driving the piezo element 14 is impressed to heighten the liquid pressure in the supply- preparation room 5 and shorten the returning period as well as curb the drawing. The opening hole 13 into the atmosphere set to the ink supply-preparation room 5 performs a role of a buffer. The opening hole 13 not only expedites a response frequency but also lets out foam into the atmosphere through the hole to eliminate  an unstable factor should foam be mixed into it.

IPC: B60S1/32
Filed: 1990-03-31
Abstract: PURPOSE:To reduce inverting noise by making pulling force work upon a crank lever in an inverting position by the rotation of a crank arm, and rotating the crank lever in an orthogonal direction to its reciprocating-rotational direction. CONSTITUTION:A wiper device 3 pushes and pulls and a rod 6 in a direction of A by rotating a motor 4, and a rotating shaft 8 is rotated reversely through a link 9 to reciprocating-rotate a movable part 10 between a lever inversion position 10a and an upper inversion position 10b. At this time, it is engaged with a slot hole 19a in a crank arm 19 at one end of the crank lever 16 journaled to a wiper head 13. A bin part 16c rotates as (a) (lower inversion position 10a)-(b)-(c')-(d)-(e) (upper inversion position 10b). Between (a) and (b), and (d) and (e), pulling force works upon the bin part 16c and the crank lever 16 rotates around a pivotally-supported shaft 12, so that the component force of a spring 17 working upon a stopping part 14a decreases to keep arm pressure to the window glass 2 of a blade smaller.

Title: Rotary wheel type extruding device for multi-hole tube
Inventor: KAMIMURA TAKATOSHI
IPC: B21C23/08
Filed: 1992-03-09
Abstract: PURPOSE:To prevent seam like defect and break of comb teeth from occurring by forming the shape of a mandrel so as to extrude stocks to be extruded by preliminarily once kneading plural stocks to be extruded. CONSTITUTION:Stocks 10 to be extruded inside two outer circumferential grooves 2 provided on the peripheral edge of a wheel 1 are forcibly pressed with the frictional force of the wheel, abutted on an abutment 11, and allowed to flow into an accumulating room 4. Inside the room 4, the stocks 10 are divided into two with a mandrel 7 near a die 5, but two stocks 10 are allowed to flow in the opening part 9 of the mandrel 7 near the wheel 1 while being kneaded to be homogenized. In such a way, since the temperature and the pressure of metals of both sides holding the mandrel 7 between are homogenized, the seam like defect is eliminated, the force exerted on the comb teeth is balanced between both sides of the mandrel and the break of the comb teeth is prevented.

Title: Film feeding detection device for camera
Inventor: SHIMADA TAKAHISA
IPC: G03B17/00
Filed: 1988-04-06
Abstract: PURPOSE:To judge whether or not a film is fed successfully with simple constitution by providing a switch means which turns on and off corresponding to the motion of a carrier. CONSTITUTION:The switch means SW4 is operated by a carrier 22 where a planetary gear 21 is supported pivotally. While no film is wound around a spool 14, the rotation of the motor 1 is transmitted to a sprocket 25 through the driving transmission system of the sprocket 25, but when a film is taken up around the spool 14, the sprocket 25 is driven through the film. In this case, the rotating speed is more speedy than the rotating speed when the sprocket is driven through the planetary gear 21, so the planetary gear 21 is flipped away to disable the transmission through the planetary gear 21. It is therefore confirmed whether or not the film is securely wound around the spool 14 by the turn-on/turn-off operation of the switch means SW4. Consequently, it is judged whether or not the film is fed successfully with the simple constitution.

Title: Image compression method and image expansion method
Inventor: NISHIDA YUKIHIRO
IPC: H04N19/00
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To improve the compression rate by setting one representative value to a map pattern when data in a block are entirely the same and setting two representative values when the data in the block have dispersion and using a difference between each representative value and a representative value of neighboring blocks for the representative value when the data in the block have dispersion. SOLUTION: A mean value (m) of a block 3 is calculated for gradation data in all picture elements 2 in the block 3 and when data are all equal, FFh is set to a map pattern. When the data are in dispersion, 0 is set for picture element groups whose value is less than the mean value (m) and 1 is set for picture element groups whose value is more than the mean value (m). Furthermore, a mean value is calculated for each group, a small group mean value a0 is set for small picture element groups whose value is less than the mean value (m) and a small group mean value a1 is set for small picture element groups whose value is more than the mean value (m).  Then a difference d0 between the small group mean value a0 and the small group means value ap0 of a neighboring block 3 is calculated, and when the difference is higher, 1 is set to a flag f0 and a0* is set to small group gradation data, and when the difference is smaller, 0 is set to the flag f0 and d0* is set to small group gradation data. Moreover, as to large groups, similarly when the difference is higher, 1 is set to a flag f1 and a1* is set to large group gradation data, and when the difference is smaller, 0 is set to the flag f1 and d1* is set to large group gradation data. Thus, the compression rate is improved.

Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To improve the preparation efficiency of a program and to improve reliability by segmenting the entire object program as one rectangular area and segmenting it for the unit of a programmable controller or a module later. SOLUTION: When preparing the program to be operated on the programmable controller by a program loader, the entire object program is segmented as one rectangular later and afterwards, it is segmented for the unit of the programmable controller or the module. Namely, an entire control function including function blocks (a)-(d) is segmented by one block frame (entire frame) 1. Thus, the program preparation of the control program is performed without caring about the programmable controller block and the module block and as one cluster, the program can be functionally divided later for the unit of the programmable controller or module.
